This research aims to identify how open educational resources (OERs) can contribute towards primary education, and what role they might play in increasing childhood literacy in particular, which has been identified as a prime component in ensuring educational attainment in primary school. Literature in the area largely addresses OERs and their potential to widen participation in tertiary education with a focus on developed nations, with little discussion about how OERs can be utilized in primary education. This thesis is particularly interested in the role OERs might play in primary education in developing nations where a range of challenges contribute to the low levels of literacy. In nations like India and South Africa, which are the locations of the case study organizations selected for this research, decentralized rural populations, combined with high levels of poverty, child labor and low levels of literacy and awareness cause poor attendance and access to schools. This research suggests that OERs aimed at developing literacy in primary school-aged children can overcome the distribution and access issues that contribute to low attendance and engagement with education in these nations. OERs have the capacity to bypass low levels of educational infrastructure by distributing high quality resources online in low definition formats suitable for downloading and under open licenses on platforms suitable for users to repackage, translate and re-purpose according to their particular need or audience. While there are a range of sustainability challenges for organizations with a social mission to use OERs to increase the equity and access of educational materials, these organizations have found innovative solutions taken from other online successes such as gaming and social media. Making use of volunteers and users in a community of practice to ensure that content is translated, quality is maintained and there is volume on their sites has some risks but also enables the maintenance of an open repository of materials for use, re-use, adaptation and sharing. This thesis contributes to the existing literature by shedding light into understanding these challenges from the experiences and perspectives of three case study organizations that provide OERs for children.
